Neuroimaging has provided fascinating insight into the dynamic nature of human brain maturation. However, most studies of developmental changes in brain anatomy have considered individual locations in relative isolation from all others and have not characterized relationships between structural changes in different parts of the developing brain. Now, new research describes the first comprehensive study of coordinated anatomical maturation within the developing human brain. The study,...

Animal study offers insights into possible drug targets to improve memory as we age Drugs that affect the levels of an important brain protein involved in learning and memory reverse cellular changes in the brain seen during aging, according to an animal study in the December 7 issue of The Journal of Neuroscience. The findings could one day aid in the development of new drugs that enhance cognitive function in older adults. Aging-related memory loss is associated with the gradual...

Like a gardener who stakes some plants and weeds out others, the brain is constantly building networks of synapses, while pruning out redundant or unneeded synapses. Researchers at The Jackson Laboratory led by Assistant Professor Zhong-wei Zhang, Ph.D., have discovered a factor in synapse-building, also showing that the building and pruning processes occur independent of each other. Mammals are born with functioning but not-yet-developed brains. After birth, external stimuli and internal...

A cognitive map enables orientation The cerebellum is far more intensively involved in helping us navigate than previously thought. To move and learn effectively in spatial environments our brain, and particularly our hippocampus, creates a "cognitive" map of the environment. The cerebellum contributes to the creation of this map through altering the chemical communication between its neurones. If this ability is inactivated, the brain is no longer able to create an effective spatial...

Researchers working with adult mice have discovered that learning and memory were profoundly affected when they altered the amounts of a certain protein in specific parts of the mammals' brains. The protein, called kibra, was linked in previous studies in humans to memory and protection against late-onset Alzheimer's disease. The new work in mice, reported in the Sept. 22 issue of Neuron, shows that kibra is an essential part of a complex of proteins that control the sculpting of brain...
